Answer:
-2
Step-by-step explanation:
- 5x + 8 = 18
Take + 8 to the right hand side, it turns negative i.e -8
-5x = 18 - 8
-5x = 10
Divide both sides by the coefficient of x which is -5
-5x/5 = 10/-5
x = -2
We'll combine the and the on the right side.
Now, we'll subtract from both sides.
Divide both sides by .
Ta-da!
